My invention lrelates to a device for turning,` cylinders through any' desired arc.

''Wliilel my device is adapted to turn any type of cylinders such as logs, tubes, etc. through any desired arc it is particularly adapted for `turning the continuous stream 4of looping bars fed from the delivery end of a continuous steaming machine through .90O so that they may be automatically fed on to the usual return coveyor leading tothe front of the machine anddeposited therefor the operative tofeed them in as usual.l My invention therefore makes possible the 'returnving of these looping bars automaticallyto the front of the m'acliine thereby dispensing with an operative formerly thought necessary in the rear of the machine totake the -bars asV they come `from the continuous stream and feed them individually onto the usual return conveyor. It is obvious, howyever, that the principles 'of;myinvention try.

inay'be'employed for automatically turning any type of cylinders in any type of indusl f These and such other objects ofmy invention as may hereinafter appear will be best understood from'a description of a specific embodiment, such as is shown in the accompanying drawings, applied,` to a continuous nithe drawirlgs,Fig;r -1 is a side elevation Y of the rear end'of a continuous steaming macliinehnaving my invention attached thereto.

The trackway 2() includes a relativelyV Vshort' plate 26 `havingfxa guide Apin 28A therefrom and l the a otherftrack--Iway 22 =is ar elevation `of theY structure ystantiallyi90-Q andy drop ,them on theusualieturn-:conveyor 11 leading to the front lof the machine. The looping barsl'l employed 4in e particularly adapted forlturning such l atype ofcylinder 14 comprising afbar, spool, or bobbin or any other type of device having -hub 16 at each end thereof although it 'is obvious that my'device maybe so modified to tu'rn any type of a cylinder without-having a hub on the end thereof. nIfdesired the-spaces between thetrackways 20and'22 may be'lle'd projecting i upwards spaced from-said: guide plate 20fsubstantial-ly the length ofa bar or cylinderll and is of a length` and curvature corresponding 'toY the y"desired number of degrees of turning'nofthe bars in the embodiment shown adapted for continuoussteamingm'achines of 90 and of an inclination suflic'ient to Vcauseone end 30-of a bar to dropbyjgravity downzsaid longer track-wayrwhile a hubi'l ofysaid-.opposi-te end 32 is retained andpivoted on said shorter plate V20 by said Vguide pin 28. Particularly where a cylinder '14 not`havingl a 'hub v16 is employed andy in theuembodiment shownthe longer track-way is provided with theretaining plate 31 onthe outeredge thereof.` The Vpivoting inclinedV track-way 20 includes means preferably `a chute to drop -the'opposite pivoting 'end 732 substantially levell and even with said freeend at the delivery end of Vsaid track-ways. f This portion of the'pivoting track-way 20 in,` `the specific einbodiw ment shown is constructed for theiparticular purpose of turning a bar 14 Yhaving 'a hub 16 on the pivoting endthereof and for Athis'purpose the guide plate 20 is provided with a T- shaped slot 34 projecting `outwards vhaving a T-base 36 of substantially the size of a hub `16 and a T-liead 38 of substantially the width of a bar terminating at the edge `ofthe plate 26` substantially opposite the-lower delivery end 40 of said longerpivoting track-way 22.

'of said guide-ways.

from said slot for dropping the opposite end 32 of said bar after it has passed through said slot 34 when said end has been turned the desired amount, in the specific embodiment shown substantially 90, for dropping it substantially level and even 7ith said free end 30 at the delivery end of said track-ways. 4ln the embodiment shown said chute 42 is additionally slightly inclined or twisted, but it is obvious that the machine may be so constructed that this need not be necessary. In order to retard the drop of the opposite end 32 of a bar 14 I preferably provide the spring 46 projecting from the inner wall of said chute 42 so that said ends 30 and 32 may be substantially level when leaving the delivery end It is obvious, however, that the pivoting track-way 2O may be con structed in different fashions such as a semispiral guide-way if desired particularly where cylinders 14 not having hubs on the ends thereof are desired to be turned.

There a continuous steaming machine is employed as in the embodiment shown it is obvious that the looping bars 14 are fed down the usual chiite 47 at the rear or delivery eiid thereof as the cloth normally looped around them in use has been taken from them. it is thus obvious that a means 48 should be provided to individually take said bars 14 from the continuous stream at the delivery end of said machine and feed them at spaced intervals on the receiving` end 24 of said trackways. lVhile any type of means may be einployed I have shown in the drawings a continuous substantially vertical conveyor 48 abutting said bars as they fall down the chute 4? having the hooks 50 thereon adapted to grasp individual bars 14 from said continuous stream and drop them at spaced i intervals on the receiving end 24 of said inclined track-ways. In the embodiment shown the return conveyor 11 having suitable means or hooks projecting upwards therefrom is provided running from the delivery ends of saidlonger track-way and chute and substantially parallel thereto and ruiming to the front fend of said steaming machine 12. When my improved turning device isused for this purpose or if desired for other purposes an inclined apron 56 is provided having an upper end 5S under the delivery ends 40 and 44 of said larger trackway 22 and chute 42 for receiving` substantially simultaneously both ends of a bar 14 ant delivering it over said apron 51 on the return conveyor 11.

For purposes of more clearly understanding the operation of the machine, l have shown cylinders oi' bars 14 in various positions spaced more closely together than in actual practice. proved device is obvious from the above de scription. rl`he continuous stream of bars is fed down the chute 46 at the delivery end of the continuous steaming machine 12. The

The operation of my in'i-,

hooks 50 on the conveyor 48 then grasp the center portions of an individual bar 14 raise it up and drop it on the delivery end 24 of the turning table 10. rl`he bar then starts t ioll down the inclined plate 2O and the curved track-way 22 until it abuts the guide pin 28, the inner end 32 of said bar abutting the guide pin and the hub 16a then embracing said guide pin; thus, while the free end 30 of said bar is freely dropping by gravity down the longer inclined track-way 22 the opposite end is iirmly held by said guide pin 2% and pivoted on the top of said plate 2() until it falls through the slot 34 down the chute 42, is braked in its falling action by the 4spring 4G and arrives at the delivery ends 40 and 44 of said track-ways substantially siniultaneously with the free end 30 so that both ends are substantially delivered at once on to the inclined apron G. The bars 14 are then individually dropped on to the return conveyor 11 and are returned in the usual manner to the front of the machine.

It is thus obvious that I have provided a novel method and means of turning any 'type of cylinder through any desired arc particularly adapted for use in turning the looping bars of continuous steaming machines from the delivery to the receiving ends thereof, in combination with an automatic feeding -conveyor for automatically feeding the bars on the turning table and a return conveyor 11 for returning said bars to the rear end of the machine. It is also obvious that the de- Avice with slight modifications is applicable for turning any type of cylinder with or without a spool or hub on the end thereof through any desired number of degrees.

It is understood that my invention is not limited to the specific embodiments shown and that various deviations may be made therefrom without departing from the spirit `and scope of the appended claims.
